本文从AdS/CFT对应关系出发，研究了六维（2,0）超共形场理论中Wilson曲面算子的算子积展开（OPE）。我们利用球面Wilson曲面算子的m5膜描述在高维表示中计算手性主算子的OPE系数。我们在计算中使用了非手性的m5膜作用。我们还讨论了它们的膜极限，并将我们的结果与膜描述的结果进行了比较。
The operator product expansion (OPE) of the Wilson surface operators in six-dimensional (2, 0) superconformal field theory is studied from AdS/CFT correspondence in this paper. We compute the OPE coefficients of the chiral primary operators using the M5-brane description for spherical Wilson surface operators in higher dimensional representations. We use the non-chiral M5-brane action in our calculation. We also discuss their membrane limit, and compare our results with the ones obtained from membrane description.
